v0.2.1

This is the initial public Studio 0.2 release, including the Monitoring, metadata, lineage and diagnostics updates prepared for this release.

• Monitoring supports DataCoolie log schemas v6 and v7, consistent visual help and hover tooltips, equal visual row heights, and performance sampling within each operation scope, including maintenance.
• Metadata editing preserves source content and delegates semantic validation to DataCoolie. Assets, lineage and diagnostic evidence use the corrected identity and cache rules.
• Base installations include PyArrow, NumPy and pytz. Release verification covers application startup, DuckDB integrations and packaged frontend serving.

Upgrade notes: older unsupported execution log schemas are excluded. The metadata validation endpoint has been removed. Complete schema17 caches migrate to schema18; rollback requires a compatible Studio application. See the complete release notes for compatibility and migration details.

pip install --upgrade datacoolie-studio==0.2.1
